Patent GB-1288048-A (GB)
IPC: G09B7/073
Filed: 1969-12-08
Abstract: 1288048 Teaching machines; selective Signalling G WESTERBERG 8 Dec 1969 [9 Dec 1968] 59801/69 Headings G4H and G5G A system, especially a teaching system, in which electric signals are conveyed between a central station and a plurality of peripheral stations, has a common cable 18 having, e.g. ten conductors connecting the central station 17 to each of the peripheral stations 11, 12, 14, 16, 128 &c. in parallel. Each peripheral station has a gate circuit consisting of resistors and/or diodes such as are shown connected to the transistor Trl in Fig. 2. At any one time, the gates of all peripheral stations except one are blocked so that only the one station can send signals to the central station. In use for teaching, the central (master) station presents a question to all the peripheral (student) stations and each student is required to make a selective response, e.g. by means of push-button switches such as 1, 2, 3, 4 in Fig. 2. By binary coding, a selection between four switches can be uniquely signalled over three of the conductors of cable 18, as shown. However, the selection made is not transmitted to the master station until the student's gate circuit is unblocked. If diodes represent 1 and resistors represent 0, the gate circuit in Fig. 2 is unblocked by a binary coded input signal representing 10100. In this way five conductors of the cable 18 can handle 32 stations each having a different binary coded address. After the students have been given time to make their selections, the master station sends to all of them a sequence of coded unblocking signals, each thus being unblocked in turn. In effect therefore, each student station is linked to the master station on a "time sharing" basis. The master station includes comparator circuitry (Fig. 3, not shown) by which the correctness or otherwise of each student's response is detected and recorded. The student's switching units may be plug-in assemblies fitting a socket block m in each of the student stations. The gate circuits would be in the plug-in assemblies so that a particular coded address would identify the switching unit of a particular student, not the station (e.g. the desk) at which he is sitting on any particular occasion.

Title: Waveform equalisation
IPC: H03H7/01
Filed: 1972-12-29
Abstract: 1421920 Pulse equalizer circuit FUJITSU Ltd 29 Dec 1972 [31 Dec 1971] 60181/72 Heading H4R A waveform equalization circuit for use in different lengths of transmission line and comprising a variable equalizer followed by a variable attenuator each controlled by a signal derived by rectification of equalized output pulses is arranged to produce from a transmitter a pulse of the same peak amplitude irrespective of the length of line in which it is inserted but waveform changes such as different widths of Guassian characteristic are tolerated provided the intersymbol interference is within acceptable limits. The requirement that the product of the line transfer function L 1  (f) and equalization characteristic Eq 1 (f) should be constant for all line lengths is dispensed with in order to deal with an adequate bandwidth. A mathematical analysis is included. Variable equalizer 13 (Fig. 6) and variable attenuator 14 are controlled by the output from a peak detector 19 and control of attenuator 14 may be by way of function generator 17. A number of variable capacitor equalizer circuits are exemplified.

Abstract: 1325718 Ampoules ASTRA AB 18 Dec 1970 [19 Dec 1969] 60295/70 Heading B8C [Also in Division A5] An ampoule comprises a cylindrical body 2 closed at one end by a piston (4) inserted in the body, and having part of the body wall radially displaced to restrain the piston against axial movement of that end of the cylinder. The ampoule is made by accommodating the body 2 containing the medicament in a bore in a die 6 and inserting the piston (4) in the end ofthe body. The body wall is then displaced radially inwards by stamping the end of the cylinder with a punching tool 7 whose punching surface 9 extends axially from the tool and whose diameter is between the inner and outer cylinder diameter so that an inwardly extending lip 11 formed to retain the piston, and the remaining axially extending wall is of reduced thickness. The punching surface 9 may be the same diameter as the cylinder outer diameter in which case an inturned edge (11a), Fig. 1 (not shown), is formed. In further embodiments Figs. 3 and 7 and 4 and 8 (not shown),inturnedtongues (11b), (11c) may be formed by a punching tool having diametrically opposed extensions (12) on the punching surface, Fig. 12 (not shown), or projections (14), (15), (16) which extend axially from the planar end of the tool to stamp out the tongues. The punching tool or the die may be heated to soften the material for punching. The end of the ampoule remote from the piston may be sealed by a membrane.

Title: Electroanalytical cell and amperometric measurement method
IPC: G01N27/49
Filed: 1979-01-08
Abstract: In an electroanalytical cell of the type used for measuring the concentration of an electroactive component, such as oxygen, in a gaseous or liquid fluid, by measuring the current between working electrode 210 and counter electrode 220 in contact with an electrolyte 299 and with a semipermeable membrane 24 separating the electrolyte from the fluid; a third guard electrode 230 is provided in contact with the electrolyte, and between the working and counter electrodes. The third electrode can be held at a potential that is effective to protect the surface of the working- electrode 210 from undesired currents and stray electronic contributions; that potential preferably being substantially the same potential as that of the working-electrode. This provides for a substantially increased accuracy of measurement, a considerable extension of the measurement range toward lower gas concentrations, less sensitivity of the cell to shocks or vibrations, and a simplification of the transient response of the cell. <IMAGE>
